On a similar note, I know attraction certainly isn't a choice, either. It's been shown that attraction is caused by various aspects related to biology.

Not to derail the subject, but I do think this goes hand-in-hand with the anti-gay standpoint that being a certain sexuality is a choice. No. What you like: sexual orientation, fetishes / kinks, who / what you're attracted to, who you love are all biological in one way or another. Also note that by "biological" I mean both mental and physical, conscious and subconscious.

I mean, you really can't force yourself to love someone. You can learn to love someone / grow to love them, but you can't just magically make up your mind like that. The notion that love and attraction are solely a choice are asinine claims, at best.

Some of these things can be affected by third-party sources (social norms and media), but honestly I'm under the impression that there isn't much of that that influences attraction.

I don't really have any sources to cite because I honestly am not really trying to argue anything, just make an isolated statement along with my own personal opinion. Do your own research on the subject if you don't believe me or something.

And while anecdotal evidence isn't always reliable, I'll just share some anyway.

I sometimes find myself being attracted to people that most people would think were odd in some way. I dunno. Just, like, for some reason I have the tendency to be attracted to some kinda dorky guys. Even now, I still have a little bit of a crush on my husband's best friend. :\ I don't see that as infidelity: I love my husband and nothing will change that, I will never leave him for someone else. I can't help it if I happen to get butterflies when I see a certain person.

Corey, I don't understand how people can see that explanation as "cold, mechanical, and primal." Cx I know that some people do, but I just don't get it. A lot of the time that comes from people that use the argument, "Oh well opposite-sex marriage is natural / gayness is unnatural!" (the latter is totally false, but that's an argument for another day). Such irony.
Forcing yourself to feel a certain feeling for someone is what I see as cold and mechanical. I also see it as dictative.
